  fix(bridge): replicate push-uplink config so every spoke node ships its own metrics to the hub

  LastSkywalker released this 2026-06-21 09:14:43 +03:00 | 123 commits to main since this release

  Confirmed cause of peer metrics not reaching the hub: metrics ride the
  off-Raft per-node stream (the topology bridge, which is leader-only, no longer
  carries them), so each spoke node must POST its OWN metrics to the hub. But the
  uplink config (hub seeds + shared secret) was persisted only to the local .env
  of the node where it was configured (SaveBridge → cv → .env, not replicated),
  so a peer like orangepi5-plus had bridge_enabled=false and never uplinked —
  only the configured node's own + the leader's connector metrics reached the hub.

  Replicate the push-uplink config through cluster_config so the whole spoke
  converges:

  • Replicator.SubmitConfigSet(key,value) writes a key into the replicated
    cluster_config (CmdConfigSet).
  • The cluster-config reconciler now also handles the bridge: the node with a
    local push uplink seeds bridge_shared_secret / bridge_remote_seeds /
    bridge_mode into cluster_config (idempotent, only while unset); every node
    adopts it and rebuilds its metric-stream bridge, so each ships its own
    metrics to the hub. Scoped to push mode — receive (hub) / both (legacy) keep
    per-node config. The topology bridge sender stays leader-gated, so followers
    don't double-ship the log.

  CmdConfigSet carrying the secret never reaches the hub: in push mode the bridge
  ships only uplinkTypes (host/topology), and the secret is seeded only in push
  mode — so it stays inside the spoke (both-mode config-sync is unchanged).
